sAsH BALANCE AND FASTENER.

SPECIFICATION forming part of Letters Patent No. 714,720, dated December2, 1902. Application tiled March 26, 1902. Serial No. 100,107. (Nomodel.)

To aZZ whom it may concern:

Be it known thatwe, FRANK J. LOWERY and FRANK EVERETT BILLINGS, citizensof the United States, residing at Fort Fairfield, in

the county of Aroostook and State of Maine,

have invented certain new and useful Improvements in Sash Balances andFasteners; and we do declare the following to be a full, clear, andexact description of theinvention,

1o such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification. l

This invention relates to new and useful improvements in window-sashbalances and fasteners, and comprises means whereby the spring-actuatedgear-wheel carried in a suitzo able casing is held from rotation andalso a spring-actuated bolt adapted to be held in engagement with arack-bar in the edge of the screen, said bolt adapted to be actuated, bymeans of a push-button, to throw the same out of engagement with therack-bar simultaneously with the operation'of the locking means,wherebythesaid spring-actuated gearwheel is allowedto rotate.

The invention consists, further, in the proo vision, in connection witha sash-fastener, of a guide-bar secured to one sash and adapted to havebearing or a ball which is adapted to l travel in a casing mounted inthe-adjacent frame.

The invention comprises various other details of construction, whichwill be hereinafter fully described and then speciiically defined in theappended claims, and is illustrated in the accompanying drawings, which,

4o with the letters of reference marked thereon, `form a part of thisapplication, and in which drawings- Figure lis an elevation of ourdevice shown as applied to the sash and frame of. a window.

Fig.2 is a vertical cross-sectional view through a portion of the casingand sash, showing the "push-button for releasing the locking mechanismcarried by the screen. Fig. 3 is an enlarged detail view of thespring-actuated bolt 5o which locks the gear-wheel. Fig. 4 is a dep tailview of the push-button. Fig. 5 is a sectional view horizontally throughthe casing, showing in top elevation the ball-carrying plate. Fig. 6 isan enlarged detail perspective-view of the antifriction-ball and themember carrying the same.

Reference now being had to the details of the drawings by letter, Adesignates the sash of a window-screen, on the edge of which is provideda rack-bar B, having a series of 6o teeth on its outer edge. Adjacent tosaid rack-bar is a casing C, which is countersunken in the frame of thewindow. In said frame is journaled a shaft D, to one end of which issecured a spring B', the outer end of said 65 spring being connected tothe gear-wheel E near its periphery. Said gear-Wheel has a number ofgear-teeth disposed along its periphery which are in mesh with the teethof the rack-bar B. 7o

Mounted to slide horizontally on the upper surface of the lower portionof the casing is a bolt F, the forward end of which is guided through anaperture in the wall of the casing adjacent to the rack-bar, and theouter end of said bolt, is adapted to engage between the teeth of saidrack-bar to normally hold the sash locked. Said bolt F has an elongatedapertn re F through the body portion thereot', and a spring G, carriedby the bolt K, 8o bears'yieldingly against a shoulderf on the bolt,which is adapted to hold said bolt normally in a locked relation withthe rack-bar. The inner end of said bolt F has an inclined edge, as atF2, which is adapted to engage in a recess Hin the end of aspring-actuated bolt K.

A spring N, -fastened at one end, as at N', to the casing, bearsyieldingly' against the upper end of the bolt K and is adapted to 9ohold the same normally in the position shown in Fig. l of the drawings,in which position the tapering end of the head F2 of bolt F is incontact with the tapering wall of the recess in the end of the bolt K.Projecting laterally from the upper end of the bolt K is a lug or stopK, which when in lockingrelation is disposed in the path of the teethot' said gear- Wheel, preventing said wheel from rotating.

M designates a push-button having a latroo erally-projecting portion M,which has an inclined edge M2, which laterally-projecting portion isadapted to be inserted in the elongated slot in the bolt F for thepurpose of having a wedging action against the end of said elongatedaperture .when it is desired to actuate the bolts longitudinally tothrow the same out of engagement with the rack-bar and cog-teeth,respectively. The inner end of said push-button is contracted, as at O,and is adapted to enter an aperture P in the wall of the casing, whilethe outer shank portion Vof the push-button has a thumb-piece or freeend Q projecting through the finishingstrip R of the window-frame. Acasing S is seated in said finishing-strip R, and a spring S' isprovided, which is seated in said easing S and bears between the innerend of the casing and the enlarged outer end Q, serving to throw saidpush-button normally out of engagement with the spring-actuated bolt F.

Mounted in a channel in the frame of the window is a casing T, which isflanged, as at T', on its inner longitudinal portion, and behind saidflange an antifriction-ball J is adapted to bear, said ball being heldby means of a socket I, which is formed at the end of a bracket-arm I',held to the sash'at any suitable location. When said ball is adjusted inposition and held by the socket member, it has a frictional contact withthe inner face of said ange, adapted to bear against the same as thewindow is raised and lowered. Said bracket-arm has a recess L adjacentto its socket end, in which the free edge of the of the gear-wheel, anda push-button for actuating said bolts simultaneously,as set forth.

2. A sash balance and fastener comprising in combination with the sashof a window, a rack-bar on the edge thereof, a casing seated in theframe of the window, a shaft journaled on said frame, a spring-actuatedgear-Wheel mounted on said shaft and in mesh with said rack-bar, aspring-actuated bolt mounted in comprising in combination with the sashof a window, a rack-bar on the edge thereof, a

casing seated in the window, a springactu' ated gear-Wheel mountedtherein and in engagement with the teeth of the rack-bar, aspring-actuated bolt F in said casing adapted to engage the teeth ofsaid rack-bar, and having a head with an inclined edge, a second bolt,spring-actuated and having a recessed end, one wall of which is inclinedagainst which the inclined end of said bolt is adapted to contact, a lug projecting laterally from the second bolt, and normally in the path ofthe teeth of said gear-wheel, a spring secured to the casing at one endand bearing yieldingly against said projecting portion, and a pushbuttonfor actuating said bolt F, as set forth.

4. In vcombination with a sash, a rack-bar mounted thereon, a casing, aspring-actuated gear-wheel mounted in said casing, a bolt F,spring-actuated and adapted to engage the teeth of said rack, ashouldered portion on said bolt, and a head with an inclined edge, abolt K with a projecting portion K on one end, the opposite end of saidbolt K being recessed, one end of said recess having an inclined walladapted to engage the inclined edge of said bolt F, a push-button havinga laterally-projecting portion with an inclined edge, which is adaptedto enter an elongated aperture in said bolt F and bear against the endof said aperture, the inner contracted end of said button designed toengage an aperture in said casing, and a spring for normally holdingsaid button at its farthest outward throw, as set forth.

In testimony whereof we hereunto affix our signatures in presence of twowitnesses.
